Male Attractiveness Is Influenced by UV Wavelengths in a Newt Species but Not in Its Close Relative

Mean (±SD) ventral spectra of Lissotriton vulgaris (left) and L. helveticus (center) tested in the experiment. Close-up on the UV range that shows the two peaks in Lissotriton vulgaris (black line) and L. helveticus (grey line) in the UV range. The dotted lines indicate the limit of the UV range.
